Get fantastic sound from your digital audio sources

How do you get sound from your PC? If you're still doing it the old fashioned way, by plugging into your computer's headphone jack, then you should definitely know about the Audioengine D1. This tiny, outboard digital-to-analog converter simply connects to one of your PC's USB ports, and bypasses your computer's built-in audio circuitry. By processing your digital music files outside the noisy environment of your computer, you'll hear far more dynamic and detailed sound that you can really savor on your headphones, powered speakers, or stereo system. The D1 also includes an optical digital input so you can enjoy similar improvements in sound with your old CD player, network music streamer, set-top box, game console, or almost any other audio device with an optical digital output.

Make your headphones sing

A pair of good headphones can give you a real taste of high-end audio without breaking the bank. But you're unlikely to find high-end sound coming out of your headphones if you plug them straight into your laptop. That's because most computer manufacturers use low-cost, low-performance circuitry to power their headphone jacks. The headphone amp inside the D1 will quickly spoil you. It delivers richer, deeper bass and clearer highs while revealing layers of musical detail that ordinary headphone jacks obscure.

Easy plug-and-play operation

Adding the D1 to a system is simple — just plug it into any USB port on your computer, where it will install itself and be ready for use in a matter of seconds. From there, just plug in your 'phones, or connect the preamp outputs to your powered speakers or stereo and you're done. The handy volume knob lets you control listening levels for both headphone and preamp outputs.

If connecting to a TV, please make sure you can select "PCM" output in its audio menu. This DAC is not compatible with Dolby® Digital signals.

Turn 1s and 0s into sweet sounding music

Why buy a separate DAC? These devices are all about getting true high-fidelity sound from digital sources like computers, streaming music players, smartphones, and more. While these kinds of sources usually have their own digital-to-analog converters built in, you can expect a separate DAC to give you much better accuracy and finer detail.

Amazing combined with a Sonos

I have my computer audioengine A2+ speakers connected through the audioengine D1. The computer is connected to the D1 with a USB cable. I then connected a Sonos into the audioengine D1 with an optical cable. I love that when I play music with the Sonos, it overrides the computer sound and just plays the Sonos music. The D1 gives priority to the optical cable, so I don't need a switch to switch between computer sound and the Sonos.

Unstable in OSX Yosemite

My D1 worked great prior to installing OSX Yosemite. Since upgrading, the sound begins to decay and start crackling and the sound eventually becomes garbled to the point it cannot be listened to. Turning the unit off, then back does resolve it temporarily. This is done several times a day. Nothing from AudioEngine to resolve the problem.

Awesome with A5+

I purchased the DAC because I wasn't getting the quality I expected out of my Audioengine A5+ speakers. After some research, I learned that the problem was likely due to the low quality headphone jack built into my Dell laptop. An audiophile friend of mine recommended the Cambridge Audio DACMagic, however, the DACMagic seemed like overkill for my computer system. Without doing extensive research, I chose the Audioengine D1 on the assumption that it would match well with my A5+ speakers. The difference was amazing. I feel like I have a genuine hi-fi system. I can hear tiny details that I never could before while listening to the same music on my iPod. I do not have exceptional hearing talents, but I can hear a difference using a DAC. Stunning combination. I get the best results from the audio files I ripped from CD or bought through iTunes. I get only a modest improvement from music I stream from Pandora One. The D1 works as intended and I am happy with the purchase.

Doesn't work with Mac OS X Yosemite

Written By Keith, Utah on Friday, January 30, 2015

Just hope the product works when you get it. If there is a problem and you contact Audioengine tech support they will tell you it is somebody else's fault not theirs. In my case they blame Apple yet they admit they aren't even working with Apple to resolve the issues. Buyer beware....

Cons:A good, full independently powered USB hub (about $20+) is needed to use this unit on laptops and other computers with USB ports that do not put out full power. On 300 Ohm headphones, the lack of USB power may prevent getting life-sized volume.

Headphone Amp Audioengine D1

I suspect it may be low in power output although im not sure thats the problem 2Vrms. It sounds great, clarity is awsome and distortion probable cant be easy to mesure.

Pros:Operation is simple to set up with optical as it puts priorty on it (PC).

Cons:Another volt in out put may or may not correct the low bass broblem. I have to crank up the low end of my EQ (PC) to max to get flat responce. But im not sure if the headphones are a part of the problem (AKG 550). Have questians I have not had time to ask, Work. Some recordings have a much higher out put than others. This could go five star once I get this nailed down.

cool

Excellent DAC that does what it is supposed to

Written By erniecolorado1, Aurora, CO on Thursday, April 24, 2014

Great product especially using Toslink port. In order to bypass the motherboard sound chip, which is always recommended in this case, since the external DAC is always higher quality by far, you need this product in USB or Toslink optical digital connections. I prefer the Toslink optical over the USB. Your motherboard needs to have the Toslink connection, which many do nowadays. If you look in the description, the Toslink gets higher resolution 24-bit/192 KHz than the USB connection does. I recommend a good Monster or Audioquest optical cable, short as you can have it. The sound is so pristine. NO background noise, no crackle or static at all. Just crystal clear sound. Get a good pair of speakers with at least a 6.5 inch bass/mid-woofer and you are good to go.

good sound but missing accessories

Written By johnny_boy, new york,ny on Thursday, February 20, 2014

I use this DAC to connect my Scientific Atlanta cable box to a set of JBL active speakers. From a sound point of view it sounds very good. No software to install. I just plugged in the toslink cable and plugged in the audioengine to a wall socket via a usb cable and ac/dc plug. The USB cable that comes with it is a joke. It is the shortest cable I have ever seen, so I had to get another one. The unit is vey small and I wish the volume control knob was bigger. Plus there are limited input types this device will accept. Another issue is it doesn't come with a usb to wall socket attachment, so you will have to buy one or use the one that came with a smartphone or some other device. But it does what I need it to do right now and it was a huge amount of money.

Delivers great sound

Not too long ago I purchased a new computer and, surprisingly, discovered it has a poor sound card. I have an iTunes music library on my computer that I like listening to through my desktop speakers. The sound that was being produced just wasn't cutting it. I did some research and found a lot of good reviews regarding the Audioengine D1. I decided to purchase one and it has proven to be a great decision. The sound it produces is very satisfying to my particular ears. Based on my experience with this product, I would highly recommend it.

Audioengine D1 Heaqdphone amp

Got mine today the 7th of January as scheduled. A definite increase in volume and overall tone on the ATH-M50's headphone. The Audioengine D1 headphone amp is worth the investment. I'll be using the D1's analog outputs for my receiver in the very near future. Coupled with Cructhfield support team, there is no way you can go wrong. Their representatives called me twice to explain the product that I ordered. I'm going to buy another for my sons birthday coming up.

Pros:All the product features; increase in volume and improved tonal quality on both of my headphones.

Audioengine D1

Seems to work fine, paired with the Audioengine 5+. Not sure if its worth the extra $$ to go with this but I did and I'm fine with it. Be aware my first D1 did not work properly, thought it was defective. Crutchfield was awesome (as usual!) with the return, then the 2nd unit behaved the same. I plugged a 2.0 USB splitter into my 3.0 port (basically downrated my computer's USB port) and it worked fine. There is nothing in the literature that tells you this, found this solution on line.

Pros:It works, makes using the Audioengine 5+ speakers a little more flexible. Purchased from Crutchfield so the problems I had were handled awesomely.

Cons:Is it worth the additional cost? Had to return 1st D1 due to incompatibility with 3.0 USB port, downrating the port solved problem.

As advertised

Bought this because the sound card in my brand new $2.5k laptop sounds like junk. This thing is awesome. Has trouble driving my Sennheiser hd600s, But they are very hard to drive. Makes my hd380s sound incredible. Paired them up with some A5s from the same company and this is the ultimate desktop audio solution IMO, suitable for casual listening, critical listening and even video/audio production. Good luck finding anything that performs as well near this price point.

D1 DAC

Over the years I have had several high-end audio systems,but limited space since I retired several years ago no longer will accommodate the large speakers and component system. While my new PC based near-field system is a significant step down from what I have been listening to, I have been very surprised and satisfied with the improved performance using the D1 DAC, This is a great product its price point.

Pros:Very compact, easy to install and performs as advertised

Cons:I wished it had two sets of line outputs, either two RCA or XLR and RCA, even if it cost a little more.

Great Upgrade

This is a great little DAC/AMP. I've used the HiFiMan HM-101 in the past and it does a great job for it's price. But this is head and shoulders above that. Immediately noticed much fuller and detailed sound through my AKG K240 MK II's. If you are looking for a much more immersive audio experience I highly recommend.

Audioengine D1 - Well worth the buy

Everyone today is interested in video entertainment, and enhancements and features for that purpose. I'm sure there are still others out there, beside myself, who love music far more. I have a great audio system, including a set of Bose 901's and a pre-amp and power-amp from Emotiva. I recently purchased the Audioengine D1 so that I could stream high quality music from my computer to my audio system. There is nothing that you have to do but connect the unit to your computer, no special software is needed. Believe me when I tell you that words cannot describe how fantastic this setup sounds. If you love music as I do, you owe it to yourself to purchase this missing link and begin to enjoy all that the internet has to offer an audiophile. Very low cost compared to other DACs on the market. Very portable. No additional power supply required, being powered by the USB power buss.

Pros:Great value and addition for playing digital files from a computer system.

Big Sound, Little Box

I purchased the Audio Engine D1 because of cost and also the Audio Engine reputation. Also, I knew that I could get more from my computer system than what my stock sound card could deliver. I also wanted to retrieve a audio through the USB port to keep things in the Digital domain. I'm using an HP desktop computer and feeding an ART SLA-1, 100watt/chnl amplifier connected to a pair of Definitive Technologies SM-350 monitors. After quickly connecting the D1 (About a minute) using the analog out, I was on my way to what follows.

First and foremost, the difference when I connected was not subtle. The Treble had much better pitch as well as greater definition. The highs were much smoother and warm while still having a great deal of detail and transparency.

The bass was another issue altogether. It wasn't as defined or as controlled and it seemed to have a distortion that wasn't present in the treble range. After a quick run through of the gain settings from the computer and iTunes, adjusting the gain structure as required everything snapped into place. Now the Bass had great pitch definition and extension. The bass was had a much better dynamics and "feel".

Vocals are uncannily real made possible by an awesome midrange. Both female and male vocals really shine, although darker male voices do come off a little lean. Artist such as Lou Rawls or Michael McDonald have a little less "amber" but all in all still pleasing and still warm sounding.

The headphone out is Very Good. I listened using Grado SR80's, Sennheiser HD280 PRO's and the Audio Technica ATM-50's. All showed improvements similar to what I wrote above, each with their own character and each one easily disguisable from the other.

For the price I can't imagine finding another DAC in this price range that could do better with as many features. I would put this in the same category as the Audio Quest Dragonfly and the HRT HeadStreamer.

Pros:A lot of Features for the money. Very Good sound in its price range. Solid Build Quality. Optical Input.

Audioengine D1

OK, but just not quite there yet. It's a bit sloppy, loses composure with more complex material. Bass seems a little thin. Headphone amp needs more power and a cleaner sound. It's an improvement over a p/c sound card for sure, but not compared to some other products in a similar price range, or for not much more.

Awesome product!

Great product. I bought it because my headphone port on my Macbook pro has some issues and wanted something to bypass it. This was absolutely the best remedy. The DAC is solidly made and the packaging is superior to most others. The sound quality is quite exceptional with good headphone/speakers. I would 100% recommend buying this!

Pros:Good sound, build quality, packaging

Cons:Maybe the price is bit high? I don't really care the DAC is too good.

Audioengine D1

Was very skeptical about this product but installed it on my iMac. Made a world of difference over the standard mic port. Amplifier is clean with no hum. Cleaned up the bass but especially the mid range. A little bit of a 3D quality. Plus I now have the mic port in front of me rather than having to reach around the iMac

Sound Great

The Audioengine D1 has great design and build quality, and the audio is really good. I'm using it with the USB connection (haven't tried the optical input yet), Windows 7 laptop, and Bose AE 2 headphones. Most of my music files are variable bit rate mp3 with a high of 328k to a low of 128k. The audio preformance has the warmth of a tube amp with the detail and clairty of a solidstate amp. I'm really like it, highly recommend.

E Rey little bit helps

I packed the D1 on my summer trip and have it hooked up to a Mac Air and Bose Soundlink Bluetooth speaker. It sounds great! I was able to easily compare it with a Bluetooth and 3.5mm cable hook-up and it's quite noticeable. There is ample bass and the midrange is clearer. If you care at all about sound quality, the D1 is a pretty inexpensive way to improve your tunes.

a worthwhile investment

This is a good unit. Its small, it provides better amplification, and you'll clearly hear the difference in the dynamic range in volume and tone. This is particularly useful if you are using full size head phones of high quality.

Pros:small, versatile, good value, great improvement over in computer amplifier

Its optical input is great!

I would recommend this to people who are considering portable DAC, including NuForce. I ordered the open box and it came in excellent condition. No scratch, no dent, no sign of use. However, the USB cable that it came with does not work. The computer cannot detect it and I could not hear any sound. So I read their troubleshooting section and switched the cable. It worked immediately! One thing I like the most about this DAC is its optical input. I do not own a receiver, so I can't use my AKG headphone to watch movie. But now I can connect this to my TV and use my headphone to watch movie or play video games without waking up other people. The size is okay, it is pretty heavy too. But then you know the build is sturdy and a lot of "meat" is packed inside. So it is not as portable as DragonFly.

Audioengine D1

This little thing is amazing. I use to always say it's crazy to spend $300.00 on a set of headphones to listen to music on your computer until I purchased the Audioengine. I for one love music,and I love how this item makes music sound great.I like jazz and old school and you can hear everything just the way its meant to sound,GREAT music just sounds great. I can listen to music all day now without disturbing others. Its not just listening to music,Its hearing the music.I would recommend this to all my friends.Great item.

Pros:Its small,It sounds great.

Cons:Could use some more power; or maybe its me.I just like BIG POWER!!!

Cleaner bass, more balanced sound

I must say the reviews I had read here on Crutchfield and elsewhere were right on. The Audioengine D1 makes a big difference in listening to music from my computer. It's not earth shattering, it's subtle but definitive. I'm using the D1 paired to an Audio-Technica ATH-M50. At first listen I noticed bass did not sound boomy as it did before (not the headphone's fault), even from a poor youtube source of the Harlem Shake. Next I tried some higher quality files from iTunes... wow! Nat Cole's vocal in The Very Thought of You were more refined, instruments were a LOT more crisp and discernible. Just about anything I listened to sounded better, as if I had been listening to music through a heavy blanket. Listening to music is even more enjoyable now with the Audioengine D1! I have only used the D1 attached via the USB port, I have yet to listen to it through the optical in. But so far it's VERY good!

Great sound from this DAC

I'm using the D1 with the PSB Alpha PS1 amplified speakers - and it is a great pairing (my PC is a home build, core i7-870, Win-7 64b w/ 16GB ram). Clean, accurate sound from my mp3's (I also have WAV files and itunes AAC as well). I use a belkin gold series 6 foot usb cable to connect with my computer, which works well (10 ft did not work for me). Setup was easy, once I switched to the 6ft cable. Windows easily recognizes the D1 and auto installs drivers. Without a doubt -- using a DAC w/ your computer is well worth it. Before this, I had always used the line out from either a basic sound card, or in my current build - the line out from the built in sound off of the MB (yea, I know- lame :) Using the DAC basically improves every part of the sound coming from your speakers - lows, mids and highs. I just got the PSB's (replaced bad m-audio av30's) - and I had a chance to use this DAC w/ the m-audio's for a couple days (before they choked)... and WOW -- amazing difference in the sound. Now, using the PSB's w/ this DAC - the sound is simply amazing.,.. I couldn't be happier (course, the PSB's are a few notches above the m-audio in quality :) Highly recommended.

Pros:Build quality, excellent sound. USB powered. Large volume control knob on front of unit. Good warranty.

Cons:A tad pricey... quality 10 foot USB cable to computer did not work w/ the D1 - presumably due to USB power requirement (6 foot worked fine -thankfully - since 2-3 foot was NOT going to cut it for my setup)

Not Bad, for the price, a keeper for sure.

Good sounds, NO ground isolation so you need to be aware of you your installation requirements. Works well with other AudioEngine components. Flawless with my Laptop, Hum (ground) loop issues with my desktop PC.

Awesome!

I researched a lot to pick the perfect DAC/AMP for work. I have the headphones on all day and the sound from the PC just wasn't good enough. I bought better headphones that helped a little but still it was not rich and full. I talked to Derrick at Crutchfield and he recommended the Audioengine D1 over the other model I was considering. I ordered it and it arrived well-packed and quickly. Installation was a snap. Windows recognized it and installed it immediately even making it the audio output. I didn't have to do anything but plug it in and insert my headphones. When I did the sound came alive. It is rich and full and the bass is more powerful and very well defined. Most people wouldn't bother for work to do this but I am here to tell you it makes listening to music at work so enjoyable the time just flies by!

Pros:Super easy to install, great music quality, good build quality, easy to use volume control knob.

Wow

For three years I've had a pair of Audioengine 2's that I've been using with my iMac. Great little speakers, but when I recently got a D1 on the recommendation of reviews- wow! The difference in clarity with 256 kbps itunes files is absolutely amazing- It's as if a blanket has been lifted from the A2's. Mids and highs are MUCH crisper, and it's not even broken in yet. I listen to everything from bluegrass to EDM, and it all sounds vastly better with greater sound separation. Just don't forget to change the Midi settings for iOS per the instructions to 96 khz and 24 bits- I was disappointed until I did that.

So much better

Written By LoveQualitySound, Silverlake, WA on Thursday, January 10, 2013

My computer headphone jack surged and blew my Rotel. VERY COSTLY. So, I bought this to remedy that issue and avoid future service repairs. I didn't expect much of a sound improvement, but it truly is a HUGE improvement in sound quality. I have a high end Gigabyte board with Realtek HD audio on-board, which I admit I was actually satisfied with. So, when I plugged in the Audioengine D1 and heard better bass control on my Boston sub, warmer and richer tones from top to bottom, I was shocked. Seriously, very excited.

Pros:For me, I like that it's small, I like that it has RCAs... It improves sound. Plug and play--took my computer five seconds before it informed me the "device is ready to use" after plugging it in. Volume control is handy.

Cons:I'd love it if this thing had HDMI. I could see how some people would want a remote with it. I understand that for some people, the fact it's small is going to be a con. It might move around. Might need some velcro? Personally, I like that it's small.

Best DAC fro the money

Seems today everyone is interested in video entertainment, and enhancements and features for that purpose. I'm sure there are still others out there, beside myself, who love music far more. I have a great audio system, including an incredible tube amplifier that my son built for me. I recently purchased the Audioengine D1 DAC so that I could stream high quality music from my computer to my system. Believe me when I tell you that words cannot describe how fantastic this setup sounds. If you love music as I do, you owe it to yourself to purchase this missing link and begin to enjoy all that the internet has to offer an audiophile.

Pros:Essentially no setup involved. The first device I ever found that is truely "plug and play". Built in high quality headphone amplifier. Extremely low cost compared to other DACs on the market. Very portable. No additional power supply required, being powered by the USB power buss.

Paired with Audioengine Speakers

I paired these up with some Audioengine powered bookshelf speakers for casual listening in my bedroom. The source is FLAC and MP3 files off my computer. The combination has a nice warm tone and does a gorgeous job with sparse arrangements like jazz combos or singer/songwriter type stuff. It has enough punch for a little rock but I don't think it is up to a massive orchestral recording. I bought it for the simpler stuff so I am quite happy listening to Feist or Fleet Foxes on it while hanging out in the bedroom. I don't like headphones much so I can't comment on it as a straight headphone amp.

8 Time World Hit Recording Artist & D1 Fan!

Let me tell you I had this D1 hooked up to my system faster than I could unwrap it from its packaging, fast and easy with instant results! Now I have to say at first I wasn't blown away when I plugged in my Sennheiser HD-600, it sounded fantastic but not overkill. However when I plugged this into my laptop controled PA I was blown away! I know my system! Well... I knew my old system, I LOVE my new system!!! I use Crown Macro Tech amps (5000i on mains, 5000i on bass) & JBL SR 4733x & 4722. I have my HP laptop going into a TC Helicon then into a Presonus mixer All connections are Monster Cable 1000's. You know I always thought this set-up was sweet but side by side after the D1...ain't no way I would want to go back without it!!! If you have a good or great system you owe it to yourself to buy one of these lil things! There was so much that was missing in the sound without it! Everything has more clarity, more alive, a richer and full sound...THIS IS ON A FLAT EQ!!! I am now buying yet another D1 for my music radio show I host (Late Night with Rob & Kris, on ghtalkradio) for my HD-600 I wear. BUY IT, YOU WILL LOVE IT!

Pros:The sound you will get!

Cons:Buy a better usb cable if you have a high end system & I wish I bought this a long time ago!

Audioengine D1

I was skeptical. My only regret is that I didn't buy this a long time ago. If you listen to your PC for music you have to own this. I have been using it for about ten hours, the directions say it takes about 40 to 50 hours to "break in"...somehow I can't imagine it can sound any better than it already does!

Better computer sound for little $$$$$

Paired with my A5 speakers, the D1 provides sound with better depth, more detail, and is simple to hookup. Music simply sounds better, particularly when encoded at a high bit-rate. Build quality is excellent, very easy to use, great value for the money. I trusted Audioengine for my speakers, they have come thru again with this DAC.

audiophile sound from a pc

audiophile sound from a pc? no way. But this litle dac will blow out your mind. Is hard to belive the quality sound coming from the computer, I found myself hearing music for hours, what a difference this litle thing make, .

Pros:clear, detailed sound, solid built.

Cons:bad recordings will sound bad, no discrimination from this small piece of electronics.

Fantastic product

This is a fantastic little product. The sound is fantastic, it is very small and handy, and it works without a hitch. I have tons of audio equipment (including three or four DACs), and this thing just rocks like the best of them. A no-brainer, as is the other Audioengine product I own, the Audioengine 2 speakers. At this point, anything this company makes in a product category I am shopping for will now be at the top of my list. And no better place to but it from than Crutchfield.

Audioengine D1

I am so amazed on how much improvement I am getting out of my iTunes music from my laptop. I got goosebumps and smiles at the same time. The sound is crystal clear and detailed. I am getting goosebumps and smiles at the same time. Wow!!. I dont know what else to say. Audioengine D1 is the way to go. I purchased mine refurbished from Crutchfield. This item looks like new. Received on time and in really nice packaging. I highly recommend this DAC if you want into better audio quality from your music from your laptop.

Pros:Small. Crystal clear audio quality. Cute and well built.

Cons:Nothig that I ca't think of, other than keeping me more awake at nights listening to my music collection.

Perfect for Mac Pro

This is the perfect compliment to the power of the Mac Pro. I can use either the USB bus or the Optical Audio to deliver crisp and clean sound to my KRK monitors. Easy set up. No drop outs ever. I love this thing!

Ultimate Upgrade!

I purchased the D1 to use primarily as a headphone amp. My PC could not drive my Grado SR80s. I knew the Grados were not the problem as the SR80s sound great when connected to my stereo amp.

When I hooked up the D1 to my computer (Shuttle XPC w/ Win7) it immediately recognized the device and installed the drivers. I was up and running in under 5 minutes and wow. I had no idea how good the music from my PC could sound. The D1 provides a crystal clear signal. Not only is the power boosted but I am no longer getting any residual hum in the background between tracks, just a clear audio signal. An added bonus of the D1 is that it has breathed new life into my old Altec Lansing ATP3 speakers. Before I hooked them up to the D1 was getting a lot of buzz and hum when I turned them up. The D1 has fixed that problem and saved me from buying new speakers (at least delayed the purchase). The D1s crystal clear signal has the speakers bumping like new. If you want decent sound from music on your computer the D1 is a must have accessory.

D1 DAC is #1

bought this little device with really no expectations of it making a huge impact on my computer audio system. was I ever wrong. I made small incremental changes to my system. first it was the new laptop (HP Entertainment), then new speakers (M-Audio AV-40), then upgraded speaker cable (Monster), then the D1 DAC. once the D1 DAC and Audioquest USB cable were installed, I noticed a significant inprovement in overall clarity, detail and tighter bass. the speakers were now free of the HP sound card and able to really open up. these speakers now sound so much larger than they actually are and play much louder. so far I am very happy with the purchase right out of the box. no break in needed. have not tried with headphones yet.

Pros:size of device
improved clarity and detail in internet music
ready to go out of the box
easy installation

Features

Overview: The D1 DAC (Digital to Analog Converter) is designed
to connect between your computer's USB port or an optical digital output, and your
audio system or headphones. It can also be used as a portable DAC (soundcard) with
a laptop computer. The two signal inputs are a USB Type-B port (USB Type-A to USB
Type-B cable included) and an optical digital (Toslink) jack. There are two outputs,
rear panel analog stereo RCA jacks and a front panel 3.5mm headphone jack. Both
outputs are controlled by the rotary volume knob on the front panel and the RCA
outputs are muted when headphones are plugged into the front panel mini-jack output.
The small switch on the front panel lights when the D1 is turned on.

Note: If connecting to a television set's optical output,
please make sure that you are able to select PCM as the default optical out
audio format from your television's Audio menu. This DAC is not compatible
with multi-channel audio signals and will not work with televisions that do
not output PCM.

Specifications:

Power Requirement: 5V/130 mA; powered by
USB (USB connection required for power even when using the
optical digital input to transfer audio signal)
